Are you referring to the official debian installation ISO's or any self 
build one?

For my self build arm64/aarch64 ISO i use the exactly same grub 
invocation you are citing, and it always starts up only the newt front 
end in the serial console.

   menuentry 'Start Graphical Installation' --hotkey=i {
        linux   /install/gtk/vmlinuz vga=788 --- quiet
        initrd  /install/gtk/initrd.gz
    }

This is the standard way, and on both i386 and amd64 it always results 
in the graphical installer to start up.
But never for arm64/aarch64.

I tried many different ways, but without success (unless using buggy 
DEBIAN_FRONTEND=gtk parameter).

I suspect there must be something else besides the mere grub configuration.

Is there maybe any mandatory kernel module or grub module needed that 
both i386/amd64 don't require?

Thanks
